Very uncommon map depicting CALIFORNIA AS AN ISLAND on the Sanson model. The Great Lakes are open-ended in the west. Santa Fe is on the banks of a river emanating from a large lake and emptying into the "Mer Vermeio" (Gulf of California). Quivira is located in present day Texas. Nicely engraved with a fine compass rose in the Atlantic. Ref: McLaughlin #202. Minor light spots in very wide margins, else very fine.
